21 Claims.

The present invention, in its broader aspects, relates to power-drivenmachinery in general, and it relates more particularly to automaticwire-stitching machines.

One of the objects of the present invention is to provide a safe andefficient wire-stitching ma chine which maybe readilyadapted for use institching any one of a wide variety of articles, and one which willperform satisfactorily at all times, which is sturdy and can withstandprolongedabuse, and which is yet producible at a relatively low cost.

Another object of the present invention-is to provide in a manner ashereinafter set forth, awire-stit'ching machine wherein the stitchinghead or unitmay be readily turned or adjusted to any one of a pluralityof positions, whereby the machine may be used for numerous applicationswhich would otherwise require the provision of several separatestitching machines.

Another object of the invention is to provide a motor actuatedwire-stitching machine having an angularly adjustable stitching-unitwith means whereby the application of power to'said adjustablestitching-unit is controlled from a re mote point disassociated fromsaid unit.

Another object of theinvention is to provide as an element of themachine an improved and efiicient arrangement for operatively unwinding,guiding and supplying wire, thread or the like, from a supply 'spoolorreel in a controlled manner under a state of tension to prevent slack.I

Another object of the invention is to provide, as an element of themachine, a new and improved cutting means for cutting the wire fedrelative to a staple forming and driving means into pre-determinedlengths.

Another cbjectof thepresent invention is to provide, as an element ofthe machine, new and improved means for safeguarding the operatoragainst accidental injury, such as commonly caused by inadvertentlyplacing ones hands between relatively approaching power-driven machineparts or members.

A further object of the invention is to provide, in a manner ashereinafter set forth, a machine of the class referred to with a drivenstructure common to a stitching mechanism in the form of a stapleforming and driving mechanism, a cutter mechanism. and a wire feedinmechanism and electrically actuated means for controlling the connectionof said structure to a prime mover.

Further objects of the invention are to provide, ina manner ashereinafter set forth, a machine of the class referred to which is comparatively simple in its construction and ar rangement, strong, durable,compact, readily assembled, thoroughly efiicient in its use, capable ofbeing quickly repaired when occasion requires, and comparativelyinexpensive to set up.

Embodying the objects. aforesaid andothers which may hereinafter appear,the, invention consists of the novel construction, combination andarrangement of parts to be more specifically referred to and illustratedin the accompanying drawings, wherein are shown embodiments of theinvention, but it is to be understood that All changes, variations andmodification-s may be 5 resorted to which fall within the scope of theinvention as claimed.

For the purpose of illustrating the invention, there is shown in theaccompanying drawings the elements of the machine which are at presentpreferred, since the same have been found in practice to givesatisfactory and reliable results, although it is to be understood thatthe various instrumentalities of which the invention consists can bevariously arranged and organized and that the invention is not limitedto the precise arrangement and organization of' the instrumentalities'asherein shown and described.

Referring to the drawings, wherein like reference characters indicatelike parts:

Figure 1 is a front elevation of a wire-stitching machine, in accordancewith this invention, having its adjustable stitching unit set to formstitches generally perpendicularly to the direction of the stitchingarm,

Figure2 is a side elevation looking towards the left of the machineillustrated by Figure 1,
